I live at 8,150 above sea level for any one that doesn't know. I have a stock engine, with MAC Shorties, MAC Off Road X-Pipe and MAC Mufflers. I also have RAM AIR Intake from MARCH, Hypertech adjustable fuel pressure regulator and a hypertech chip, which recommends high octane. Should I run the cheap stuff. I know living way up in elevation I don't receive a whole lot of good O2. So my car needs to go lean or it will choke its self out.

What I hear on the website is that you want to go with the least amount of octane as you can. How much do you think I should advance my base timing? 12, 14, 16. I don't want to hear any pinging. Maybe I should bring it up to ping and back it off.

I'm sure there is high octane up here, because some manufactors recommend it. I'm sure that Gas Stations like to make the extra money also.

Thanks
